 The S800 electronics includes a Mesytec CFD (MCFD), used to "filter" the detector signals going to the Scaler and Mesytec TDC. The configuration parameters of the CFD (thresholds, delays, fraction, etc.) can be remotely adjusted via a MCFD GUI developed by the NSCL DAQ group. During tuning of the S800, one typically needs to adjust thresholds only. The S800 electronics includes a Mesytec CFD (MCFD), used to "filter" the detector signals going to the Scaler and Mesytec TDC.

-The S800 DAQ can be run in Standalone mode (as described above), or in Slave mode. The later means that the S800 DAQ is controlled by an external DAQ (e.g. GRETINA). In this mode, the S800 ULM receives external clock and external synchronization  signals from the master DAQ. Running in Slave mode requires to change the script **CC0105Begin.tcl** in directory **/user/s800/s800daq/Scripts**. In this file, there are two variables ''extsynch'' and ''extclock'' to define if the external synchronization and clock signals are enabled (=1) or disabled (=0). Make sure that you set these variables to 1 if you want to run in Slave mode.+The S800 DAQ can be run in Standalone mode (as described above), or in Slave mode.

-By default, when running in Slave mode, data are recorded in the stagearea of the Master DAQ (experiment account). It is however possible to record simultaneously data from the S800 into the S800 stagearea, using the ''multilogger'' option (see ReadoutGUI figure above). The S800 ReadougGUI offers the possibility to record data from four different S800 ring-buffers: rawccusb, rawvmusb, s800built, and s800filter. The later is the most important since data from this ring buffer can be immediately processed by the S800 SpecTcl. +By default, when running in Slave mode, data are recorded in the stagearea of the Master DAQ (experiment account).
